…with Greek-key topology; it is a subclass of immunoglobulin-like fold. The R domain binds to a cell surface receptor, permitting the toxin to enter the cell by receptor-mediated endocytosis. The diphtheria toxin has the same mechanism of action as the enzyme NAD(+)—diphthamide ADP-ribosyltransferase (EC…
